The pink streak in Sweeney's hair doesn't bother me. Unlike Koslow's blue streak, I could actually see Sami wanting that in her hair. I could never see Kate wanting a blue streak in her hair, so it never quite fit with her. I like it on Sami though, and I like Sweeney's reason for it. I'm just glad she didn't go full out trying to copy Aguilera, LOL.

I do actually agree from a character perspective, but they've yet to acknowledge it on Sami.
